dissapearing fish

[beta novice]

so i have had a bunch of fish go missing from my tank for example my 2 female bettas from my sisters tank and some other fish idk if they died or not i am trying to figure it out any ideas would be helpfull

[StarBetta]

is your tank covered? If not then they probably jumped out or something. Maybe they got stuck under the gravel so check under there but if they are under the gravel they might be dead already. Are there any other fish larger than the females in there? Be sure to check EVERY SINGLE decor in the tank.

If you have an open tank then I would look around the tank area just to check and see if they jumped out. If so, it looks like you need to lower your water level (surface of the water lower down to prevent them reaching the top of the tank when they jump).

As StarBetta previously mentioned also, it may be the case that they are underneath the gravel (unlikely, but still possible), you may want to dig your hands into your substrate and swish around, if they are stuck unfortunately I can hardly imagine that they are alive.

Also, how hard are you looking? You never know, if you have any decor/plants (live/artificial) try to lift it (of course if you have live plants, don't lift those) and have a real good search.

Finally, are there any other fish in the tank that are larger than the betta? I trust that you wouldn't put a sorority with larger fish that are threatening to bettas so I can't imagine that being the case, thought I'd put it out there.

this happened a while ago single betta each time 55 gallon tank its closed looked in the gravel the only bigg thing in the tank was the pleco and the goldfish which has since died

This is quite the mystery! Would you happen to have any cats? They can be pretty skilled if they really want something.

[Reece]

Very strange, I doubt it was the pleco.

[StarBetta]

Yeah, it can't be the pleco, I have 2 plecos and they are scared of my bettas!

we have a cat it doesnt go in my sisters room if it does i kick it out

[Reece]

This will sound horrible but have you looked inside of your filter? Some fish can be very good at getting into them. I just wonder if one got in but not back out.

I've had one int he past be sucked up the filter. I heard it thank god and he only had a scar on his face for a few weeks. If you have snails in your tank...the fish could have died and the snails would make a fast meal from it. They take their cleaning seriously. I've had a few minnows dissapear over the last year.
